Diane Keaton says she used to suffer from the eating disorder bulimia while dating Woody Allen, who directed her in the film "Annie Hall."
The 65-year-old played Allen's love interest in the movie, which earned Keaton her only Oscar. She details her eating disorder in her new memoir, "Then Again," which was released on Tuesday, November 15.
Keaton describes consuming large meals, including desserts made up of "chocolate-covered almonds with a quart-sized bottle of 7Up," and "one Sara Lee pound cake and three Marie Callender's frozen banana cream pies," and says she secretly threw up her food.
"It's pathetic that the demands of bulimia outshone the power of my desire for Woody, but they did," she says in the book. "Woody didn't have a clue what I was up to in the privacy of his bathrooms. He did marvel at my remarkable appetite, saying I could really 'pack it in.' Ever vigilant and always on the lookout, I made sure he never caught me."
Keaton and Allen, 75, dated in the 1970s, when she was in her 20s, and she has starred in eight of his films.
In 1968, she made her Broadway debut in the musical "Hair" and famously refused to appear nude with the rest of the cast. She did, however, appear naked fora fleeting moment in the 2003 film "Something's Gotta Give," which starred Jack Nicholson and earned the actress her fourth Oscar nomination.
Keaton told CBS News, when asked about the matter years later: "Life changes. And also I believe I have a very different attitude about my body. What I'm happy about with my body these days is that it works, that it functions, that I can walk."
Keaton was later cast in Allen's New York play "Play It Again, Sam" and starred in it from 1969 to 1970. She was nominated for a Tony award for her role and later starred in a film adaptation. Her breakthrough role came in 1972, when she was cast in "The Godfather."
"Annie Hall" was released in 1977 and won four Oscars, including individual awards for Keaton and Allen. The romantic comedy is said to be based on the actress' real-life relationship with Allen. The two broke up about two years after its release.
Keaton says he never addressed her bulimia but was aware of "how insecure" she was and sent her to a psychoanalyst. The actress adds that she does not think her eating disorder stemmed from "lack of parental affection," adding that her mother gave her "everything" she desired, although she cited her parents' bickering and subsequent divorce.
Keaton, one of the most respected actresses in Hollywood, has in recent years appeared in films such as the romantic comedy "Morning Glory" with Harrison Ford (pictured, above). She continues to act and is set to appear in the 2012 films "Darling Companion" with Kevin Kline and "The Wedding" with Robert De Niro, Susan Sarandon, Topher Grace, Katherine Heigl, Amanda Seyfried and Robin Williams.
Keaton says in her book that "nothing remains of my former craving," adding: "I'm not remotely drawn to the preparation of food. I'm not hungry. I've had it all, and I've had enough. When I was a bulimic, constantly balancing the extremes of impulsivity and control was sort of like performing. After I stopped throwing up, acting - my lifelong chosen profession - came back into the picture."
